Consult an orthodontist experienced in adult skeletal expansion. A CBCT scan, orthodontic records, and, if indicated, an ENT evaluation will help determine the most appropriate treatment plan.

Hello . As per your given history of narrow upper jaw with cross bite and underbite , constricted airway might also be Deviated Nasal Septum. This requires a proper Treatment planning and diagnostic analysis like CBCT .

Based on your description, a narrow upper jaw associated with a crossbite and mild underbite may be an indication for maxillary expansion. MARPE (Miniscrew-Assisted Rapid Palatal Expansion) is one of the treatment options used in adolescents and adults to widen the upper jaw when conventional expansion is less effective due to fusion of the palatal suture. Expansion may help improve the width of the upper jaw and can sometimes increase nasal cavity space, which may improve nasal airflow in selected patients. However, breathing difficulty from one side of the nose can also be caused by conditions such as a deviated nasal septum, enlarged turbinates, allergies, or other nasal issues

Hello, At 18 years of age, MARPE (Miniscrew-Assisted Rapid Palatal Expansion) can be a suitable treatment option for patients with a narrow upper jaw, crossbite, and airway concerns. However, whether it is the best option for you depends on a detailed clinical examination and CBCT evaluation. MARPE may help: • Expand a constricted upper jaw • Correct certain types of crossbite • Create additional space for teeth alignment • Improve nasal airway dimensions in selected cases Since you also mention an underbite, the overall jaw relationship needs careful assessment, as some patients may require additional orthodontic or orthognathic treatment. I recommend consulting an Orthodontist for a complete evaluation and treatment planning. Regards, Dr. Mohit Gautam BDS, MDS (Endodontist)

For your problem , you need a systematic evaluation of your airways with dynamic MRI or polysomnographic evaluation. If narrow arch is the problem then surgical orthodontics and traditional orthognathic surgery will be of significance in your case as it will treat your malocclusion and skeletal discrepancies. You could go to consult a maxillofacial surgeon expertise in orthognathic surgery

.Miniscrew-Assisted Rapid Palatal Expansion (MARPE) is an advanced, non-surgical treatment used to widen a narrow upper jaw in adults and older teens; widens the nasal cavity, significantly improving airflow and reducing snoring. The estimated cost for MARPE in Bangalore generally ranges from ₹50,000 to ₹90,000. The final price depends on the specific expander brand used and the complexity of your bone structure. Determining if you are a candidate requires a physical clinical evaluation and a 3D CBCT scan to check your palate's bone density.We would love to help you plan your treatment.

Hi!! It can be done for sure since you are young and the bone is still mouldable , it would be great if you could share some Intraoral pictures if you have any, so that I could guide you , cost will be anywhere between 70k-1L if you are getting it done in Delhi , as not everybody does this procedure, few specialists are there who do it , and hence the higher cost, rest if you could share pictures , I could guide you further.

Refer to orthodontist.

Before going for dental treatment,  need to check with an ENT specialist to know the root cause for mouth breathing like adenoids and if it is still persistent better to take treatment. Simultaneously we can start and correct the upper jaw  through expansion device.
